Blood is the circulating __ of the body. It is the principal medium by which the biochemical homeostasis of the cells and the interstitial fluid is being maintained, in spite of both endogenous and exogenous influences. This regulation is brought about by its capacity to perform important functions.

Physical properties of blood
color - arterial and venous? reaction specific gravity pH viscosity |
arterial: bright red due to high levels of oxygen
venous: darker, dull red due to decrease levels of oxygen reaction: -- specific gravity: -- pH: 7.35 - 7.45 viscosity: 3-5x thicker than water; viscosity is increased by the presence of blood cells and the plasma proteins, and this thickness contributes to normal blood pressure |
